spotfire 如何在计算列中显示趋势
spotfire how to show a trend in a calculted column
我有这样的数据table。我如何创建一个计算列来显示数量是否在增加？说如果最后一个数量高于倒数第二个数量，那么结果应该为真否则为假。
最终，我想用一个图形table和一个图标来表示它。
谢谢
这里有两个答案，具体取决于您是想按产品查看还是仅查看整个数据集。
按产品
- 插入计算列：
Rank([Date],"asc",[Product]) as [ProductRowNumber]
- 插入计算列：
If([Quantity]>Min([Quantity]) over (Intersect([Product],Previous([ProductRowNumber]))),"TRUE","FALSE")
忽略产品（整个数据集）
插入计算列：Rank([Date],"asc") as [RowNumber]
插入计算列：If([Quantity]>Min([Quantity]) over (Previous([RowNumber])),"TRUE","FALSE")
结果
+------------+---------+----------+------------------+-------------------+-----------+-------------------------+
| Date | Product | Quantity | ProductRowNumber | IncreasingProduct | RowNumber | IncreasingEntireDataSet |
+------------+---------+----------+------------------+-------------------+-----------+-------------------------+
